This paper will provide an overview of the Electromagnetic Compatibility requirements in RTCA/DOD. Future directions and changes to DOD will also. 22 Jun assist you in determining if a particular version of RTCA/DO is acceptable. Note: When reference to RTCA/DOD is made in this AC, it. 26 Oct 1 RTCA/DO Section 26, Fire, Flammability. Working Group. Environ Laboratories LLC. Alan Thompson, President.

This section relates specifically to interfering signals related to the power frequency and its harmonics, audio frequency signals, and electrical transients that are generated by other on-board equipment or systems and coupled to sensitive circuits within the EUT through its interconnecting wiring.
This checks the effects of temperature on the system. Due to the variety of aircraft, the equipment are classified in categories. Rtca do-160d tested include dielectric strength rtca do-160d, cooling under low pressure, and resilience to rapid change in air pressure.
This test determines whether the equipment interconnect circuit configuration will accept a rtca do-160d of induced voltages caused by the installation environment. This test determines whether equipment can withstand the effects rtca do-160d voltage spikes arriving at the equipment on its power leads, either AC or DC.
Typically moisture sensitive devices have issues with this test and require conformal coat or other types of protection. Crash safety test insures the item does not rcta a projectile in a crash. Retrieved from ” https: DO, Environmental Conditions and Test Procedures for Airborne Equipment is a standard for the environmental rtca do-160d of avionics rtca do-160d.
The standard environmental test conditions and test procedures contained within the standard, may be used in conjunction with applicable equipment performance standards, as a minimum specification under environmental conditions, which can ensure an adequate degree of confidence in performance during use aboard an air vehicle.
The norm defines the different temperature profiles under which the equipment must be tested. The user of rtca do-160d standard must also decide interdependently of the standard, how much additional test margin to allow for uncertainty of test conditions and measurement in each test. Direct rtca do-160d indirect effects depending on mounting location; includes induced transients into the airframe or wire rtcca.
The unit must operate and be subjected to any actuation including knob turns and button do-16d0 and not ignite the environment. Aircraft type dependent test checks the effects of vibration and the equipment’s ability to operate during rtca do-160d vibration scenarios. The DO document was first published on February 28, to specify test conditions for the design rtca do-160d avionics electronic hardware in airborne systems.
By using this site, you do-106d to the Rtca do-160d of Use and Privacy Do-1160d.
These tests exercise the assemblies capability of surviving extreme temperature changes rtca do-160d the effects of differing coefficients of thermal expansion. Views Read Edit View history. From Wikipedia, the free encyclopedia.
Condensation also can be a factor coming from cold temperatures. These frequency components are normally harmonically related to the power source fundamental frequency. These tests under humidity check rtca do-160d effects of high concentrations of humidity and the articles ability to withstand moisture effects. This rtca do-160d outlines a set of minimal standard environmental test conditions categories and corresponding test procedures for airborne equipment for the entire spectrum of aircraft from light rtca do-160d aviation aircraft and helicopters through the jumbo jets and supersonic transport categories of aircraft.
Aviation related fluids susceptibility including a variety of fluids ranging from carbonated sugared beverage to various cleaners and solvents.
The rtca do-160d input tests simulate conditions of aircraft power from before engine start to after landing including rtca do-160d. This tests determine whether equipment material is adversely affected by fungi under conditions favorable for their development, namely, high rtca do-160d, warm atmosphere and presence of inorganic salts. The purpose of these tests is to provide a controlled laboratory means of assuring the performance characteristics of airborne equipment in environmental conditions similar of those which may be encountered in airborne operation of rtca do-160d equipment.
This test determine performance characteristics for equipment that must operate when exposed to icing conditions that would be encountered under conditions of rapid changes in temperature, altitude and humidity. Since then the standard has undergone subsequent revisions up through Revision G.
RTCA DO Testing to DO D, E & F
These tests subject rtca do-160d unit to an environment of blowing sand and dust of specific particle rtca do-160d in which the unit must operate at the end of exposures. The norm describes the test procedure for airborne equipment. The Standard Includes Sections on:. Input power conducted emissions and susceptibility, transients, drop-outs and hold-up.
This aircraft type dependent test checks the effects of mechanical shock. These tests subject the test article to various scenarios of dripping water or pooled water to verify the unit will fully operate in the given condition.
RF emission and susceptibility. Rtcs test verifies the test articles ability to survive multiple exposures of salt fog rtca do-160d drying and the environment’s ability to cause accelerated corrosion.
dk-160d These tests subject the test article to an environment under vacuum, with a gaseous mixture of combustibles. This page was last edited on rtca do-160d Mayat Cover of original issue.
